Paradigm
electronics has updated one of their most popular subwoofers. The new
Servo-15 v.2 Subwoofer plays louder and deeper than its predecessor,
the original Servo-15. With three times the RMS power output of the
Servo-15, the Servo-15 v.2 is able to produce 121 db without distortion
and is accurate to 10 Hz according to Paradigm.
The Servo-15 v.2 features Paradigm’s proprietary 15” high-excursion
bass driver which has more than 2 inches of peak-to-peak cone travel
that promotes deep bass response. The next-generation mineral-filled
copolymer polypropylene cone, with RCR Resonance Control Ribs, is
engineered for high power and low levels of distortion. The rigid,
lightweight design of the three-inch, eight layer bifilar aluminum
voice coils promote greater stability and support during extended cone
travel according to Paradigm.

The
Servo-15 v.2’s dual spiders and oversize long-travel suspensions
encourage extended cone excursion while maintaining control over cone
movement. The 29 lb. magnet structures generate a large magnetic force
field while minimizing inductive distortion. With this in mind, the
instrumentation-grade accelerometer is designed to withstand the
driver’s extreme changes in motion. Other features on the Serrvo-15
v.2’ driver include a high-pressure, die-cast aluminum chassis, a
proprietary AVS cooling and a large extruded aluminum ventilated center
heatsink.

Inputs include both RCA and balanced; control facilities include auto
on/off, trigger on/off, subwoofer level control, continuously variable
phase control from 0-80 degrees and bass contour, which allows for up
to +6 dB boost at 60 Hz.

Paradigm also believes the amplifier’s precision components and
dual-sided military spec (FR-4 rated) glass/epoxy circuit boards ensure
performance and long term reliability. The advanced output stage is 10
times faster than conventional Class-D designs for superior efficiency.

Safety features on the amplifier include a proprietary voice coil
temperature sensor, an amplifier temperature sensor and short circuit
protection which reacts within 10 microseconds.
